FileTransfer Upload Progress does not work

File Transfer Upload progress has stopped working as of version 3.0.0. I suspect it has something to do with sending the JS from a different Thread as we are also experiencing issues with the DOM not redrawing (although updating just fine) with our custom media plugin (we send JS from a different thread, see: https://github.com/auphonic/cordova-plugin-media/blob/master/src/android/AudioPlayer.java#L125 ).

Please let me know if these are two separate issues and if I should create a separate issue for both but I strongly suspect that this has something to do with each other..
